## Question

The pediatric rapid response team is reviewing children with acute respiratory distress. Drag each cue cluster to the pattern it most strongly supports.

**1.** Harsh, seal-like cough with inspiratory stridor at rest and subcostal retractions

Select a category
Lower-airway obstruction
Upper-airway obstruction
Impending respiratory failure

**2.** High fever, muffled voice, drooling, and sitting upright with neck extended

Select a category
Lower-airway obstruction
Upper-airway obstruction
Impending respiratory failure

**3.** Sudden distress while playing with small beads, unilateral wheeze, and asymmetric chest movement

Select a category
Lower-airway obstruction
Upper-airway obstruction
Impending respiratory failure

**4.** Expiratory wheeze, prolonged expiration, and hyperresonance on percussion

Select a category
Lower-airway obstruction
Upper-airway obstruction
Impending respiratory failure

**5.** Bilateral expiratory wheeze, coarse crackles, and recurrent nighttime cough

Select a category
Lower-airway obstruction
Upper-airway obstruction
Impending respiratory failure

**6.** Wheeze improves after albuterol but still has tachypnea and mild intercostal retractions

Select a category
Lower-airway obstruction
Upper-airway obstruction
Impending respiratory failure

**7.** Cyanosis, decreasing respiratory effort, and drowsiness

Select a category
Lower-airway obstruction
Upper-airway obstruction
Impending respiratory failure

## Explanation

Inspiratory stridor, a barky cough, drooling, and tripod positioning indicate upper-airway obstruction. Expiratory wheeze and prolonged expiration indicate lower-airway narrowing. Retractions, nasal flaring, grunting, cyanosis, decreasing effort, a silent chest, and altered consciousness signal severe distress or impending failure.

## In-depth explanation

Quick answer
The correct classification requires distinguishing the phase and quality of abnormal breath sounds, the presence of focal versus diffuse findings, and the trajectory of respiratory effort. Upper-airway obstruction is supported by inspiratory stridor, a barky cough, and posturing that opens the airway. Lower-airway obstruction is supported by expiratory wheeze, prolonged expiration, and hyperresonance. Impending respiratory failure is supported by cyanosis, decreasing effort, and altered consciousness, regardless of the underlying cause.

Why this is correct
Each cue cluster contains overlapping features that could appear in more than one category. For example, a barky cough and inspiratory stridor are upper-airway findings, but subcostal retractions alone could also indicate lower-airway disease or impending failure. The key is to weigh the dominant pattern: inspiratory noise and airway-opening postures point to upper-airway obstruction; expiratory noise and hyperinflation point to lower-airway obstruction; and hypoxemia with reduced effort points to impending failure.

Clinical picture
In pediatric respiratory assessment, the phase of the abnormal sound is critical. Inspiratory stridor suggests narrowing at or above the thoracic inlet, while expiratory wheeze suggests intrathoracic airway narrowing. A silent chest with decreasing effort is an ominous sign of fatigue and impending respiratory arrest. Focal wheeze after a choking episode suggests foreign body aspiration, which may present with either inspiratory or expiratory sounds depending on the location of the obstruction.

Memory hook
Use the mnemonic 'UPPER-LOWER-FAIL': Upper airway = Inspiratory stridor, barky cough, drooling, tripod. Lower airway = Expiratory wheeze, prolonged expiration, hyperresonance. Failure = Cyanosis, decreasing effort, altered consciousness.

NCLEX decision rule
Classify by the dominant phase of the abnormal breath sound and the presence of systemic signs of hypoxemia or fatigue. Do not classify based on a single finding that is common to multiple categories.

Why the alternatives are wrong
If a cue cluster includes both inspiratory and expiratory sounds, determine which is more prominent and whether there are signs of impending failure. If a child has wheeze that improves with bronchodilators but still has tachypnea and retractions, the wheeze is lower-airway, but the persistence of increased work of breathing may indicate a need for closer monitoring rather than a different category.

## Clinical scenario

Pediatric respiratory assessment
Interpret the phase and quality of breath sounds, work of breathing, air movement, oxygenation, and level of consciousness.

## Key concepts

- **Inspiratory stridor** — A high-pitched, musical sound heard during inspiration, indicating narrowing of the extrathoracic airway, such as the larynx or trachea.
- **Expiratory wheeze** — A continuous, high-pitched sound heard during expiration, indicating narrowing of the intrathoracic airways, such as the bronchi or bronchioles.
- **Impending respiratory failure** — A clinical state characterized by hypoxemia, hypercapnia, and fatigue, often manifesting as cyanosis, decreasing respiratory effort, and altered level of consciousness.
